Advantages of organic fertilizer

In recent years, my country has vigorously promoted organic fertilizers instead of chemical fertilizers and reduced the amount of chemical fertilizers. Why do we use a lot of organic fertilizers? What are the benefits of applying organic fertilizer to agricultural production? Let’s take a look!

Improve soil fertility

95% of the trace elements in the soil are in insoluble form and cannot be absorbed and utilized by plants. Microbial metabolites contain a large amount of organic acids. These substances are like hot water added to ice. It can dissolve trace elements such as calcium, magnesium, sulfur, copper, zinc, iron, boron, molybdenum and other essential mineral elements of plants, and turn them into nutrient elements that can be directly absorbed and utilized by plants, greatly increasing the soil’s fertility supply capacity.

Improve soil quality and promote the reproduction of soil microorganisms

Organic fertilizers can multiply the microorganisms in the soil, especially many beneficial microorganisms, such as nitrogen-fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, etc…. These beneficial microorganisms can decompose the organic matter in the soil, increase the soil aggregate structure, and improve Soil composition.

Microorganisms multiply very fast in the soil, they are like an invisible web, intricately intricate. After the death of the microbial cells, many tiny pipes are left in the soil. These tiny pipes not only increase the air permeability of the soil, but also make the soil fluffy and soft, and the nutrients and water are not easily lost, which increases the water storage of the soil. Fertilizer capacity avoids and eliminates soil compaction.

Provide comprehensive nutrition for crops and protect crop rhizomes

Organic fertilizer contains a lot of nutrients, trace elements, sugars and fats needed by plants. The CO2 released from the decomposition of organic manure can be used as a material for photosynthesis. Organic fertilizer also contains 5% of nitrogen, phosphorus, and potassium, and 45% of organic matter, which can provide comprehensive nutrition for crops. At the same time, it must be mentioned that the organic fertilizer is decomposed in the soil and can be transformed into various kinds of humic acid. It is a kind of macromolecule substance with good complex adsorption performance and a good complex adsorption effect on heavy metal ions. , Can effectively reduce the toxicity of heavy metal ions to crops.

Enhance crop resistance to disease, drought, and flood tolerance

Organic fertilizer contains vitamins, antibiotics, etc., which can enhance crop resistance and reduce or prevent diseases. After the organic fertilizer is applied to the soil, it can enhance the water retention capacity of the soil, and can enhance the drought resistance of crops in drought conditions.

At the same time, organic fertilizer can also loosen the soil, improve the ecological environment of crop roots, promote root growth, enhance root vitality, improve crop tolerance to waterlogging, reduce plant mortality, and increase the survival rate of agricultural products.

Improve food safety and greenness

The country has long clearly stipulated that the excessive use of inorganic fertilizers must be restricted in the agricultural production process, and organic fertilizers are the main source of fertilizer for the production of green food. Since the various nutrients in organic fertilizers are relatively complete, and these substances are completely non-toxic, harmless, and non-polluting natural substances, this provides the necessary conditions for the production of high-yield, high-quality, and pollution-free green food.

Increase crop yield

The beneficial microorganisms in organic fertilizer use the organic matter in the soil to produce secondary metabolites, which contain a lot of growth-promoting substances. For example, auxin can promote plant elongation and growth, abscisic acid can promote fruit maturity, gibberellin can promote flowering and fruit setting, increase the number of flowering, fruit retention, increase yield, make the fruit plump, fresh and tender, and can be marketed early. Increase production and income.

Reduce nutrient loss and improve fertilizer utilization

The actual utilization rate of chemical fertilizers is only 30%-45%. Part of the lost fertilizer is decomposed and released into the atmosphere, part is lost with soil and water, and part is fixed in the soil and cannot be directly absorbed by plants. When organic fertilizer is applied, the beneficial biological activities improve the soil structure and increase the soil’s ability to retain water and fertilizer, thereby reducing the loss of nutrients. Coupled with the effect of the beneficial microorganisms to dissolve phosphorus and potassium, the effective utilization rate of fertilizers can be increased to more than 50%.
